Eastman 5.12kWh 48V Low-Voltage Lithium Battery (ES51.2-100LP)

Product Overview

The Eastman ES51.2-100LP is a heavy-duty, low-voltage (LV) Lithium Iron Phosphate (LiFePO4) battery designed for high-performance solar storage and reliable home backup. Available through Powernest Limited, this 5.12kWh unit is built with “Made in India” industrial expertise, offering a robust alternative to standard lithium packs. It is specifically engineered for the 48V ecosystem, making it a perfect match for hybrid inverters from Deye, Victron, and GoodWe. With its advanced cell technology and high cycle rating, it provides a stable and safe energy foundation for years of daily cycling.

Key Features

• Industrial-Grade Longevity: Rated for over 6,000 cycles at 80% Depth of Discharge (DoD), providing a lifespan that can exceed 15 years under typical residential usage.

• Smart LCD Monitoring: Unlike many standard batteries, this unit features a built-in color LCD screen on the front panel. It provides real-time data on battery capacity, voltage, temperature, and cycle count at a glance.

• Active Cooling & Heat Dissipation: Designed with a metal casing and intelligent thermal management, ensuring the battery remains cool and efficient even during high-current charging and discharging in tropical climates.

• Massive Scalability: Supports parallel connection of up to 15 modules, allowing you to expand your system from a single 5.12kWh unit up to a massive 76.8kWh bank without needing complex external controllers.

• High Discharge Performance: Supports a 100A continuous discharge current, allowing a single module to output up to 5kW of power to support heavy household loads like pumps, heaters, and kitchen appliances.

• Safety & Compatibility: Features a sophisticated Battery Management System (BMS) with multi-layered protection. It supports CAN & RS485 communication, ensuring seamless integration with almost all major hybrid inverter brands.
